Yes, but not enough. Read the original post. 

You begin with one expert skill, two adept skills and three apprentice skills. The rest are novice. If you want to buy another expert skill (as an example) you have to sell two adept skills. You would then have two expert skills and three apprentice skills. If you then wanted a master skill, you would have to sell both your expert skills. Then you'd have one master skill and three apprentice skills. 

You can't have a master skill, an expert skill and a few adept and apprentice skills besides that. It doesn't add up. Do you understand?

Do keep in mind Railen has been a thief since he was eight. So he's had plenty of time to master those skills.

That doesn't matter.
